[0029] Please refer to Figures 1 to 7This embodiment provides a model airplane toy, comprising a fuselage 100, a battery 200 and a drive assembly 300 fixedly mounted on the fuselage 100, and wings 400, a horizontal tail 500, and a vertical tail 600, each detachably connected to the fuselage 100. The fuselage 100 defines an inner cavity 110 for securely mounting the battery 200 and the servo assembly 800. The inner cavity 110 communicates with the outside world via an inner cavity opening, to which a hatch 700 is detachably attached. The inner cavity 110 can be opened or closed by attaching or detaching the hatch 700 to the inner cavity opening, facilitating assembly and disassembly of the battery 200 and the servo assembly 800, as well as subsequent maintenance.

[0030] The fuselage 100 is constructed from two fuselage shells glued together. A detachable frame 120 is fixedly attached to the fuselage 100 adjacent to the inner cavity opening. It is understood that a positioning plate for the detachable frame 120 is exposed on one side of the inner cavity opening. This positioning plate is abuttingly connected to the hatch 700, allowing one end of the hatch 700 to be detachably connected to the inner cavity opening. A recessed retaining groove 111 is provided on the other side of the inner cavity opening. This retaining groove 111 is removably plugged into and secured to the hatch 700, allowing the other end of the hatch 700 to be similarly detachably connected to the inner cavity opening. Furthermore, a motor slot 112 is provided on the fuselage 100 adjacent to the detachable frame 120. This motor slot 112 communicates with the inner cavity 110 and is used to securely mount the drive assembly 300 to the fuselage 100.

[0031] The detachable frame 120 has a cavity 121 recessed on either side of the fuselage 100. These cavities 121 are designed to removably accommodate the wing 400. The inner wall of cavity 121 is formed with at least one plug-in block, which is formed from the inside out. It is understood that the plug-in blocks described in this embodiment are a first plug-in block 1211 and a second plug-in block 1212. The first plug-in block 1211 has a first jack 1213 for communication with the outside world, while the second plug-in block 1212 has a second jack 1214 for communication with the outside world. The detachable frame 120 also has a through-hole 122, which connects the inner cavity 110 to the second jack 1214, forming a channel in the detachable frame 120, allowing the conductive wires on the wing 400 to pass through the channel and extend into the inner cavity 110. The detachable frame 120 is also equipped with an adhesive plate 123, which is a flat, circular plate arranged around the outer periphery of the detachable frame 120. Adhesive plate 123 is adhesively fixed between the two fuselage shells of the fuselage 100, ensuring a more secure and stable connection between the fuselage 100 and the detachable frame 120. A positioning plate 1231 is vertically mounted on the adhesive plate 123, with at least a portion of the positioning plate 1231 extending outside the fuselage 100. Specifically, a portion of the positioning plate 1231 is exposed on one side of the inner cavity opening. The positioning plate 1231 is designed to engage with the elastic U-shaped buckle of the hatch cover 700, thereby preventing it from tilting upward away from the inner cavity opening.

[0032] The fuselage 100 is further provided with a connecting rod hole 130, a first receiving platform 140, a second receiving platform 150, and a connecting hole 160 at the tail. There are two connecting rod holes 130, which are arranged on opposite sides of the fuselage 100. The connecting rod of the servo assembly 800 can be movably inserted into the connecting rod hole 130, so that the connecting rod in the inner cavity 110 can pass through the connecting rod hole 130 to connect the horizontal tail 500 and the vertical tail 600 outside the inner cavity 110. The first receiving platform 140 is located at the end of the fuselage 100. It is understood that the first receiving platform 140 is provided with a positioning groove 141, which is used to allow the horizontal tail 500 to be quickly adapted and connected to the first receiving platform 140 through the positioning groove 141. The second receiving platform 150 is arranged adjacent to the first receiving platform 140. The second receiving platform 150 is provided with a fixing groove 151 on the side away from the first receiving platform 140. At least a part of the vertical tail 600 can be movably accommodated in the fixing groove 151, and the inner wall of the fixing groove 151 is recessed with a clamping groove 152 for clamping and fixing the vertical tail 600. The clamping groove 152 can prevent the end wall of the vertical tail 600 from warping up, thereby increasing the connection strength and connection aesthetics between the vertical tail 600 and the fuselage 100.

[0033] It should be noted that a first fixing plate 170 is embedded within the first receiving platform 140. This first fixing plate 170 comprises a first main plate 171 inserted and embedded between the two fuselage shells of the fuselage 100, and a tail rod slot 172 secured to one end of the first main plate 171. At least one fixing hole 1711 is provided on either side of the first main plate 171. This fixing hole 1711 is exposed within the positioning slot 141 and exposed to the fuselage 100 through the connecting hole 160. A support rod 173 is inserted and secured within the tail rod slot 172. This support rod 173 extends in the same direction as the tail of the fuselage 100 and is inserted and secured within the fuselage 100. This support rod 173 serves as the tail frame of the fuselage 100, enhancing the structural toughness and stability of the fuselage 100.

[0034] The battery 200 is electrically connected to the drive assembly 300, which includes a motor 310 secured to the motor slot 112 and propellers 320 secured to the rotating shaft of the motor 310. It will be appreciated that the battery 200 provides operating energy (electricity) for the drive assembly 300. Upon receiving a start signal, the drive assembly 300 activates the rotating shaft of the motor 310 to rotate the propellers 320, thereby providing flight power for the model aircraft toy.

[0035] There are two wings 400, each comprising an integrally formed insertion section 410 and a wing section 420. The insertion section 410 is removably adapted to be inserted into the chamber 121. A first slot 411 matching the shape of the first insert block 1211 and a second slot 412 matching the shape of the second insert block 1212 are recessed within the insertion section 410. It will be appreciated that the wing section 420 is provided with a wing rudder plate 421 and a mounting slot 422. The wing rudder plate 421 is swingably connected to the wing section 420. A wing servo 430 is fixedly mounted within the mounting slot 422. The swing arm 431 of the wing servo 430 is connected to the connecting rod 4211 of the wing rudder plate 421 via a connecting rod. The above arrangement allows the wing servo 430 to swing the swing arm 431, driving the connecting rod to pull the connecting rod 4211, causing the wing rudder plate 421 to swing on the wing section 420. By adjusting the angle of the wing rudder plate 421, the flow state of the airflow on both sides of the wing 400 is differentiated, thereby achieving flight adjustment of the model aircraft toy in the desired direction. The wing section 420 is also recessed with a first groove 423 and a second groove 424. The first groove 423 is connected to the second slot 412 and can be connected to the second socket 1214. The second groove 424 is embedded with an insert 440. The insert 440 extends into the first slot 411 and is removably inserted and fixed in the first socket 1213. That is, when the insertion section 410 of the wing 400 is inserted into the corresponding cavity 121, the first insert block 1211 is inserted into the first slot 411, the insert strip 440 is inserted into the first jack 1213, and the second insert block 1212 is inserted into the second slot 412, and the first groove 423 is connected to the second jack 1214. Simultaneously, the first groove 423 communicates with the mounting slot 422, allowing the conductive wires of the wing servo 430 to be stored in the first groove 423 and enter the inner cavity 110 through the channel formed by the second jack 1214 and the through hole 122, thereby establishing an electrical connection between the wing servo 430, the battery 200, and the circuit board in the servo assembly 800.

[0036] The horizontal stabilizer 500 includes a central connecting block 510 and first stabilizer bodies 520 located on either side of the central connecting block 510. The central connecting block 510 is adapted to be connected to the first receiving platform 140. It is understood that the central connecting block 510 is provided with a positioning block 511 that can be inserted and fixed in the positioning slot 141. The central connecting block 510 also has a connecting slot 512 that connects to the second receiving platform 150, enabling the connecting slot 512 to cooperate with the second receiving platform 150 to adapt to the vertical stabilizer 600. Furthermore, the central connecting block 510 is provided with through holes 513 extending between the positioning block 511 and the connecting slot 512. The number of through holes 513 is the same as the number of fixing holes 1711, and the two are arranged in a one-to-one correspondence. The horizontal stabilizer 500 is swingably connected to a first rudder plate 530. A first rocker arm 531, which is connected to one of the connecting rods of the servo assembly 800, is fixedly connected to the first rudder plate 530.

[0037] The vertical tail 600 includes a second tail body 610 and a second fixing plate 620, which are fixedly connected. The second tail body 610 is adapted to be connected to the connecting slot 512 and the second receiving platform 150. A fixing block 611 is integrally formed on the second tail body 610. The fixing block 611 is removably received within the fixing slot 151 and can be moved to be fixed within the retaining slot 152. It is understood that the side wall of the fixing block 611 facing away from the retaining slot 152 is designed as a sloped structure to facilitate the player's quick and easy removal of the fixing block 611 from the retaining slot 151. A slot 612 is provided on one side of the second tail body 610, which is adapted to the shape of the pins of the second fixing plate 620, allowing the second fixing plate 620 to be inserted and embedded in the second tail body 610. A second rudder plate 613 is swingably connected to the other side of the second empennage body 610 opposite to the fixed block 611 . A second swing rod 6131 connected to another connecting rod of the servo assembly 800 is fixed to the second rudder plate 613 .

[0038] It will be understood that the second fixing plate 620 includes a second main plate 621, pins 622, and fixing legs 623. One side of the second main plate 621 extends outward to form the pins 622, and the other opposite side extends outward to form the fixing legs 623. The pins 622 are rectangular plates that are inserted and embedded in the slot 612, enabling the second main plate 621 to be fixed to the outer end surface of the second empennage body 610. The number of fixing legs 623 is the same as the number of fixing holes 1711, and they are arranged in a one-to-one correspondence. The fixing legs 623 can be inserted into the through holes 513 and connected to the corresponding fixing holes 1711. The fixing legs 623 and the fixing holes 1711 are fixedly connected by screws.

[0039] That is, when the horizontal stabilizer 500 and the vertical stabilizer 600 need to be installed on the fuselage 100, the middle connecting block 510 of the horizontal stabilizer 500 is first adapted to be connected to the first receiving platform 140 so that the through hole 513 is aligned with the fixing hole 1711 and the connecting hole 160. The fixing block 611 is then placed into the fixing slot 151 and moved into the locking slot 152. The vertical stabilizer 600 is then rotated so that it can be adapted to be connected to the connecting slot 512 and the second receiving platform 150. At this time, the fixing foot 623 is inserted into the through hole 513 and connected to the fixing hole 1711. Finally, a threaded member (e.g., a screw) is placed into the connecting hole 160 and tightened to secure the fixing foot 623 to the fixing hole 1711. It is understood that when the horizontal stabilizer 500 and the vertical stabilizer 600 need to be disassembled, the above steps can be reversed.

[0040] One end of the hatch cover 700 is provided with a latch block 710 that detachably engages with the securing slot 111. The other end of the hatch cover 700 is provided with an elastic U-shaped buckle 720. The movable end of the elastic U-shaped buckle 720 is provided with a retaining foot 721 that abuts against the positioning plate 1231. The movable end of the elastic U-shaped buckle 720 movably extends from the hatch cover 700. As will be appreciated, due to the elasticity of the elastic U-shaped buckle 720, the elastic force of the elastic U-shaped buckle 720 allows it to remain in the position where the retaining foot 721 abuts against the positioning plate 1231, thereby securing one end of the hatch cover 700 to the inner cavity opening. To open the hatch cover 700, the elastic U-shaped buckle 720 is pushed to move the retaining foot 721, separating it from the positioning plate 1231. The end of the hatch cover 700 is then pulled to separate from the inner cavity opening.

[0041] The servo assembly 800 includes a mounting base 810, a circuit board 820, and two tail servos 830. The mounting base 810 is fixedly connected to the inner cavity 110 and includes a first mounting plate 811 and a second mounting plate 812 fixed in parallel. The circuit board 820 is fixedly connected to the first mounting plate 811. The circuit board 820 is electrically connected to the battery 200, the motor 310, the wing servos 430, and the tail servos 830. Two tail servos 830 are fixed adjacent to each other on the second mounting plate 812. The swing arms 831 of the two tail servos 830 are connected to the first swing rod 531 and the second swing rod 6131 through a connecting rod, so that the tail servo 830 can drive the connecting rod to pull the first swing rod 531 to drive the first directional rudder plate 530 to swing on the horizontal tail 500 through the swing of the swing arm 831, or drive the pull rod to pull the second swing rod 6131 to drive the second directional rudder plate 613 to swing on the vertical tail 600, so that the flow state of the airflow on both sides of the horizontal tail 500 or the vertical tail 600 is different, thereby realizing the flight adjustment of the model aircraft toy in the desired direction.

[0042] In summary, the wings 400, horizontal tail 500 and vertical tail 600 provided in this embodiment are all detachable, so any component can be directly replaced when damaged, and the servo assembly 800 is built into the inner cavity 110, which can increase the service life of the servo assembly 800 and ensure the appearance and authenticity of the model aircraft toy.

[0043] For clarity, certain features of the present invention described in the context of separate embodiments may be combined in a single embodiment. Furthermore, various features of the present invention described in the context of a single embodiment may also be used individually or in any suitable subcombination.
